My understanding is that it IS encrypted, and its supposed to use the Signal protocol (Signal developed it and released it for others to use)

The problems are with

• metadata (like the other comment explained)
• closed source, so we take their word on it for how it works. It's possible they're being misleading or doing something shady

See this image from a few years ago:

Note that signal does require this, which isn't in the chart:

• phone number (for now)
• last active date
• sign up date (I think)
